A registry task that clears a registry at the end of a request.

You may also provide an optional condition block, which is called and passed the Rack env to determine whether the registry should be cleared. If no condition block is provided, the registry is always cleared.

#initialize(registry_, opts_ = {}, &condition_) ⇒ ClearRegistry

Create a new ClearRegistry task. You must provide the registry and an optional condition block. If you set the :before_request option to true, the registry clearing will take place at the beginning of the request rather than the end.
